"Our policy just identifies areas where it could be sold, if it was to be approved."
The council's bylaw only needs minor amendments, and they will need consultation.
The bylaw is fantastic, councillor Josh Chandulal-Mackay said, because it is so restrictive.
"It would be pretty difficult to approve any application. It's a great policy, very artfully done, whoever is responsible for it," he said.
The bylaw was a team effort, Whanganui Mayor Hamish McKay said, made when Annette Main was mayor.
"We did get an artful solution."
Safer Whanganui manager Lauren Tamehana said a working group was looking at a project about methamphetamine.
Councillors adopted the proposed review. Consultation will begin on August 31.
